Põletikufaasis

Põletikufaasis refers to the inflammatory phase of wound healing. This is the initial and crucial stage following injury, where the body's primary response is to protect the wound site and begin the repair process. It typically lasts for the first few days after the injury occurs.

The inflammatory phase is characterized by a series of physiological events. Immediately after injury, blood vessels at the wound site constrict briefly to minimize bleeding. This is followed by vasodilation, where blood vessels widen and become more permeable. This increased permeability allows plasma fluid and immune cells, such as neutrophils and macrophages, to move from the bloodstream into the injured tissue. These cells are essential for cleaning the wound. Neutrophils arrive first to engulf and destroy bacteria and debris, preventing infection. Macrophages then follow, continuing the cleanup process, removing dead cells and releasing growth factors that initiate the next stages of healing.

Key signs of the inflammatory phase include redness, heat, swelling, and pain at the wound site. These are all indicators of increased blood flow and the immune response at work. While uncomfortable, these symptoms are a normal and necessary part of the healing cascade. The duration and intensity of the inflammatory phase can be influenced by factors such as the size and depth of the wound, the presence of infection, and the individual's overall health. Proper management of the wound during this phase, including cleaning and protection, is vital to ensure effective healing and prevent complications.
